A.I. was fantastic until Spielberg put his twist on it. You can totally tell where he added his own flare at the end (aliens? really?). Damn you for being dead, Kubrick!
Suckerpunch was pretty bad. I didn't go in with high expectations and it still let me down.
Human Centipede was shit once you got past the WTF factor.
When I fist saw American Psycho in the theater i didn't really get it and nearly walked out, it's grown on me though.
Indiana Jones and the Crystal Skull made me die a little inside.
And then there was Ralph Bakshi's Fire and Ice....i can only take so much rotoscope and crap voicework.
There are plenty of worse movies but I think the hatred for Uwe movies is pretty much universal
